Mini giants and giantesses zombie apoc

This was an alternate universe where every person was a mini giant and mini giantess around the heights 15ft tall to 19ft tall!

So the year was 2029 and the and the world has gone to shit as a deadly disease or virus as it wipe out most of humanity, and everyone became an undead zombie as the dead has risen and now there were militaries, navy, and everyone across the world who been hit by this virus are doing whatever it takes to survive. It’s either by going solo, in groups, or seeking shelter, either way people must have a weapon because the zombies are no joke, they will kill and eat any living person they come across, some walk, others run, some may have special abilities, but what matters most is survival. So god be with you all!
